"Ecodirect.com is the best ! They are such
a pleasure to work with! They offer all the
best brands at the best prices. Special
thanks to Renée who always answered my
questions on the spot, sharing her real
knowledge and giving me the best advices."

"The experience I had with my purchase was
very good. The items I ordered arrived when
I expected & were packaged well. My overall
purchasing experience was very
positive."

- Thank you,
Marlene

"I recently found EcoDirect & have been
extremely happy with their service. They
have had all the PV modules, inverters,
optimizers and accessories I needed. They
provide excellent customer service & turn
orders around very quickly. I have switched
to EcoDirect for all my parts & materials
orders. Highly recommended."

- Zeno

"I wanted to let you know I am very pleased
with the service you gave & the quality &
condition of the solar panels I received
from EcoDirect. I will purchase more items
in the future from EcoDirect and will be
sure to tell others about your fine
operation."

Thanks,
Maurice

"Thanks EcoDirect! My solar system is up
and running; waiting for City and San Diego
Gas & Electric inspections this week; so
far so good!"

"I enjoyed ordering what I needed. It was
simple and fast, no issues what so ever. If
I need something else and its at a good
price, I will defiantly order from here
again. Also the shipping is at a good
price."

- Simon

My shipment arrived on time, as predicted.
Very, very good performance by EcoDirect.
What more could you ask for from an online
material supplier? Looks like the quantity
from Quick Mount is spot on & the rails
were bundled safely. EcoDirect will be my
recommended source to my friends &
neighbors for solar.- Thank you, Jim

I have always been happy with their
customer service and prompt delivery of
products."

Enphase Micro Inverters for Solar

Using the Enphase Micro Inverter system dramatically increases the performance of your solar power system. The Enphase Micro-inverter shifts DC to AC conversion from a large, centralized inverter to a compact unit attached directly to each solar module in the power system. The Enphase Enlighten monitoring system provides unprecedented visibility into the performance of every solar module.

With the Enphase Micro-inverter System, installers are no longer limited by string design, marginal designs, co-planarity, and matched modules. Additional modules can be added as needs and budgets grow without requiring the replacement of a large centralized inverter. The Enphase MPPT algorithm works at each solar module in an installation and achieves greater than 99.6% accuracy. This enables it to maximize energy harvest at all times, even during variable light conditions!

Solar Power Challenges

Solar power production is affected by various factors such as module mismatch, obstruction shading, inter-row shading, and obstacles such as dust or debris. In addition, non-uniform changes in temperature, irradiance, and shading create complex current-voltage curves, further affecting energy harvest. This is due to the fact that in traditional systems the performance of the entire system is dictated by the performance of the weakest module.

The Enphase Solution

The Enphase Energy Micro-inverter System solves solar power challenges by performing Maximum Power Point Tracking (MPPT) at each solar module. MPPT is an algorithm used to calculate and respond to temperature and light changes detected on a solar power system, and to determine how much power to draw from the module. In contrast, centralized inverter MPPT algorithm sees the entire solar power system as a single module, and responds to the lowest production numbers it detects.

Increased Productivity

The Enphase MPPT algorithm works at each solar module in an installation and achieves greater than 99.6% accuracy which enables it to maximize energy harvest at all times, even during variable light conditions. Tests show systems using Enphase Micro-inverters increase energy harvest by as much as 25% over systems using traditional inverters.

More Reliable

Traditional centralized inverters implementations create a single point of failure for solar power systems. If the inverter fails, the entire system is disabled. Enphase Micro-inverters convert power independently at each solar module. If one micro-inverter fails, the rest continue to operate as usual. Also, if a micro-inverter is damaged or fails, it can be replaced during routine maintenance or when convenient, further reducing maintenance costs.

Reduced Operational Costs

With the Enphase Micro-inverter System, installers are no longer limited by string design, marginal designs, co-planarity, and matched modules. The space, heat, and noise associated with a large inverter are eliminated. Enphase Micro-inverter Systems improve mechanical integration, reduce wiring time, and remove the need for DC switching points.

Flexibility

Another benefit of the distributed Micro-inverter design is the potential for installations to be expanded over time. An initial set of solar modules can be installed and additional modules added as needs and budgets grow without requiring the replacement of a large centralized inverter.

Compliance and Reliability

The Enphase Micro-inverter is CSA Listed per UL1741 and can withstand surges of up to 6kV. Enphase Micro-inverter Systems undergo rigorous testing including HALT and HASS, ensuring reliability. Independent testing by Relex a leading third party reliability expert has shown an estimated Mean Time Between Failure (MTBF) of 365 years for Enphase Micro-inverters.
